    Something for the weekend?

    The weekend is almost over sir.

    But I agree, for anything reasonably useful 3d printing as it is, would be fairly useless. The only thing I've seen it used for personally is rapid prototyping (even though the slow printing speed could hardly be considered rapid)

    £10,000 per prototype, or £500 per prototpe. Makes a big difference, and is still much faster. Sure when it comes to the final prototype, we still splash out on the expensive 10k one, it's all the failed prototypes we've saved the money on.

        When there was a deadline of Friday then it focussed the mind. Now there is the whole weekend in which to hit the press. So cutting the lawn, washing the dishes, another coffee etc are all welcome distractions - time in which to consider yet another refinement of the text. When does the weekend deadline technically end - midnight or just before the London offices open their doors?

      In the interests of the global community that read this excellent publication, the weekend is not yet over and will not be until Monday has come to its inevitable conclusion in Baker Island in the Pacific Ocean (UTC-12).

      For the mystified, this weekend in the almighty, gun-toting, US of A is Labor Day weekend and Baker Island is a US territory. Now if you want the last inhabited piece of America then that would be Midway at UTC-11.

      I have a cunning plan.

      Using your totally inadequate 3D printer. create your widget, but with one slight adjustment, reduce its dimensions by 5mm all round for solid objects or 5mm bigger for hollow objects. Oh, and replace that corn starch with candle wax if poss.

      Now spray the outside or inside or I suppose both sides with a suitably conductive material.

      Take this and immerse it in a bath of whatever metallic based solution you desire and apply some volts.

      After a few years have passed (yes, yes, it is blue sky off the cuff thinking after all) and 5mm of metal has been deposited on the artefact, remove and melt away the wax or corn starch.

      Hey prestoish you have a copper coat hook or other such invaluable trinket to swank in front of your friends.

      CAD is as old as gods dog - make your own models ffs.

      Or you can download 1000's of stl files, you just have to look. (there's even a strandbeeste model you can d/l for nothing)

      There are plenty of 'cheap' 3d scanners about with the same form factor as the hobbyist printers. Plus the nature of the community is such that I am sure a replacement hot end that contains a laser, that can scan, is minutes away from market as we speak.

      Thus spake the bloke getting a 3d printer next payday.

      I don't make claims that I will be able to print a working suspension bridge or anything 'structural' any time soon... or at all really, for me it's just a really cool toy.

      On the whole I sort of agree with dabbsy the current state of the art is not great just like the early digi cams, but people didnt buy them cos they took great pictures, they bought them cos they were digital!

      and if they had not bought them, then we would all still be taking pictures on little slivers of plastic... or actually not taking pictures at all, cos it was such a pain in the arse.

    Like an 8 pin dot matrix printer...

    I think (and tell people who can remember them) that 2014 3D printing is like 1982 dot matrix printing. Noisy, slow, bumpy, feint, fanfold fed (didnt fit A4 folders) monochrome etc.

    I used it to print program listings. I tried to print graphics. I had an old moveable type press for crisper output. Other people used linotype? systems to produce blocks of text that were pasted up and rephotographed to make print plates. I had a pen plotter for linear stuff. Horses for courses.

    But I too hate the media hype around 3D printing - and I do remember massive media hype around 'desktop publishing'.

    Like the dot matrix printing dumped the pins...3D printing will probably dump the squirty plastic nozzle of curent designs in order to move on. But it is the software that is also driving this revolution. Slicing CAD models for printing is like the screen dump printer driver I wrote : part of the system that can make a useless lump of mechanism perform better, and the basic ideas of rasterising/slicing form the basis for newer mechanics to perform better.

If 3D printing to going to become a device for mass production then the whole idea needs to move away from printing in layers to someone a bit more, well, 3D really.

      Re: Title goes here

      I don't think the technology will ever go away from, as you accurately describe it, "printing in layers". That's the nature of digital versus analog ... there's nothing between 0 and 1 to smooth out the result, just a quantum leap from point A to point B. Just as with digital photography, digital audio, and digital "fill-in-the-blank", the trick is to make the increments so small that the normal human cannot differentiate between digital and analog. Although you can always zoom in to a point where you can see the difference, at normal consumption levels the two types of product are essentially the same.

      Disclaimer: Yes I have a (relatively) new 3D printer (ALS plastic type). And yes, so far its more of a toy than a tool ... but its a really fun tool to play with, and that's the whole point!

      2nd Disclaimer: I'm an American. I have a Bachelors in Physics and Masters in CS. I own and shoot guns. And there's no way in hell I would ever fire a weapon that included (even in low-pressure areas) printed components outside of an isolated safety chamber. I'm nuts, but not stupid.

        I think you missed Alice Dobb's point.

        Outside of the plastic printers, there are metal 3D printers who can produce metal components (think aerospace industrial grade).

        One company did produce a 1911 made from such a printer. (Not sure how many rounds were actually fired.) They did it just to show that it can be done and that you can produce parts that can withstand the pressure.

        Of course the company didn't say how much this gun costs, other than one could purchase several regular guns combined, far cheaper.

        Where the 3D printing can be interesting isn't producing the gun itself, but in producing the silencer/suppressor. (Again metal printer. Not plastic)

    Other uses for 3D Printers

    Where I worked they acquired a 3d printer because someone was throwing it away (It was expensive and I don't think the original purchaser got much use out of it) and they have managed to put it to great advantage to allow improvements to be explored on container handling automation, especially around predefined failure points since printed components are cheap (ignoring printer cost) compared to fixing automation after collisions. I doubt they'll ever do anything more than print these components as these are now obsolete – but it has enabled them to save replacing the systems and improve them.

    I have seen where a 3D printer has been used to build a model of a human throat and lungs from medical scan to understand where inhaled drugs are going - something that would have been difficult and expensive using conventional methodologies.

    Like a lot of things, the real use advantages for 3D printers will take time to develop and probably not resemble what was hyped for them.

  8. Novex

    3D printing definitely has more development to undergo before it's particularly useful to the masses. But even then it will never replace mass production outright as the economies of scale just can't be matched.

    So it will pretty much always be used for niche items such as: replacement parts for things now out of mass production (like car engine parts); small runs of bits for satellites (I believe NASA already do this); one-off body parts like prosthetics and other medical uses (bio printing of organs for replacement is already being done); hobbies (like the food printing mentioned, or any other art or craft); or prototyping, as already mentioned.

    The biggest thing yet to be sorted out is the 'finishing' of parts. There needs to be some kind of addition to the process that cleans up the final printed part so that it feels like it's been mass-produced. Currently that finishing still has to be done by hand.

    That said... Every damn lie about technology eventually comes true. Facial recognition was a damn lie ten years ago, maybe even five. Now it's almost true.

        I think the point being made was that once a claim (like Fermat's conjecture) had actually been proven true, then we can appreciate just how much of a lie (or self-delusion) the original claim was. (“Cubem autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et generaliter nullam in infinitum ultra quadratum potestatem in duos eiusdem nominis fas est dividere ... Cuius rei demonstrationem mirabilem sane detexi hanc marginis exguitas non caperet.”)

        Oh all right (you'd think no one understood latin any more!): “It is impossible for a cube to be written as a sum of two cubes, or a fourth power to be written as the sum of two fourth powers, or, in general, for any number which is a power greater than the second to be written as the sum of two like powers ...

    I'd like to make some complex brackets but I don't have the CAD skills, and doing iterations at Shapeways is too slow and too expensive.

    There some things that need to happen:

    1. Printers need to be cheaper. Getting there.

    2. We need color. It makes a huge difference for anything other than a pure structural part. I can't paint worth a damn.

    3. We need metal. When we do make the structural parts, they need to last more than 20 minutes without snapping.

    4. We need some way of making items other than drawing them from scratch in CAD. That's an artistic talent very very few people have. Current 3D digitizers need to get an order of magnitude better, and digitizing things is always going to run into IP issues.

    There's one application right now that I'm surprised no one's captured:

    You know all those blokes that make Airfix Spitfires? No? Because the kit's been discontinued? How about those guys that make motorcycle kits? No?

It'd be like e-books, a company'd never need to discontinue a kit because they no longer take up space in a warehouse.

      4 - what you are basically saying is along the lines of you want to write poetry but can't be arsed to learn grammar or spelling!

      CAD is the easy part, autocad is no more or less complex than word, but FEA, which is what you really need, that can be a bit more complex. While the tech is fascinating, what you are trying to do is inherently complicated. if you can't stand the heat...

      Don't know where you are getting your info on scanners from but +- 50 microns seems pretty accurate to me. and kinda the point of the current 3d printing enthusiast scene is actually making stuff you have designed, not replicating something that some other bloke/bloke-ess designed. so i would say the need for scanners is not so great. (unless making prosthetic limbs, where a model of the stump would be important!)

      Especially as the materials and construction methodology do not make 3d printing much of a candidate for replacing _any_ component. An injection moulded nylon doh-dah is going to be far stronger than it's ABS laminar print lookalike. and if the nylon doh-dah broke in the first place, then it dont look good for the printed replacement.

    A cursory glance at my back catalogue of product reviews through the 1990s and 2000s reveals I was extremely critical of digital photography and inkjet printing in their early days, and look where they are today.

    Yes, in the former, you have "professional" models which start at hundreds of pounds (or dollars) more than the "snapshot" models solely because they have interchangeable lenses (which themselves merit a second mortgage), and in the latter, you have cheap, efficient machines which work wonders provided you can put a third mortgage on your house to supply them with ink.

    1. Steven Raith

      Re: PROGRESS!

      Without wishing to be that guy, there's a shitload more to an SLR than just having replaceable lenses.

      Unless your snapshot camera can take shots ten times a second, correctly evaluated, at 16mp each, and fire them off to a storage device for 50 shots at a time in RAW format, natch (although I believe quite a few compacts can shoot in raw and have pretty wide/open lenses for shooting in darker scenes, too).

      SLRs compared to a point n shoot are like a boutique gaming PC compared to a mid-range tablet in terms of power and scope for expansion. You don't have that power and scope for expansion without having more sophisticated internals, and that increases the cost.

      Completely agree about inkjets though - most people would probably be better off with a cheap laser and using their local print shop/online service for the 1 in 1000 colour images/photos they need - or the once in every three months they print something only to find the heads have clogged up, and they have to use half a cartridge just to clean the damned thing out.

      IME very few people actually need to be able to print off photos in high quality and those that do tend to do it often, and tend to a fairly high end printer for it, and so accept the cost of ink as part of the process.

        On color lasers. They turn out to be excellent PROOF printers 'this is what the thing will look like sire, once printed' and cost effective in the sub 100 or thereabouts print runs. And even a bit higher once you factor in the cost of liasing with the printshop and collecting the results.

        As far as photos go., nope, we take those to the color photo lab and get them done on proper photographic paper, if a 'hang on the wall' print is what we want.

        Color inkjets should be banned on humanitarian grounds, as being a form of cruel and unusual punishment.

        Even my old massive A1 inkjet which cost a fortune would still block and clog if it wasnt used on every color at least once a week.

    Overhyped perhaps, but still useful

    I built a home 3D printer from a kit 8 months ago. I agree that 3D printing is often over-hyped and too slow for mass production, and most of the things I have printed have been ornaments or parts related to 3D printers. However, I have also printed some genuinely useful parts, including parts to assist my disabled mother with daily living, and parts to assist with my own electronic circuit manufacture and test. To me, the 3D printer is an alternative to carving such parts from wood or cutting them out from plastic sheet - with the advantage that if I don't get the design perfectly right first time, I can just modify it and print again..

    ABS is actually remarkably solid for most stuff you'd want to use if for - from brackets, to door handles, to project containers, etc - I can print off a caribiner that will hold my weight in 30 mins for example - now that would be stupid - I'd buy a caribiner… and there is the issue - don't print out things you can BUY, you print out things you need that don't exist, or (as in the case of my Stubilizer project) prototype stuff.

    If you are not a DIY/hobbiest or someone in need of prototyping - then don't buy one. If you are - you'll be wishing you bought one years ago. I've put through about 5kg of ABS in the last year - and had a lot of fun, learned new skills and build some cool stuff.

    Time and time again thought you meet folk that ask 'have you printed a gun', and 'can i download and print something'… both of which is to entirely miss the point.

      can i download and print something

      That ought not to be missing the point (athough today, it probably is).

      It ought to be able to download the CAD details for just about any plastic artefact, so that you can manufacture your own spare for any plastic widget or cover that gets broken. However, it's not in a product manufacturer's interests to make them available. They'd far rather we bought a whole new hairdryer or whatever. Some have even been known to build in weak spots to encourage things to break sometime after the warranty has run out.

      Perhaps what is needed is a breakthrough in 3D scanners to parallel 3D printers, so you could just dump your broken pieces into a 3D scanner and then have the computer reassemble the details of a whole one and print it for you. No CAD expertise then needed.

    Digital photography and inkjets...

    While digital photography seems to have matured(I still can't take a decent picture, though... but now I can't blame the camera), inkjets are a different matter...

    Sure, some of them now has ink that costs less than high-end perfume, and sure they print pretty pictures... then they start clogging...

    Porn industry and 'emerging technology'...

    As there are now flexible materials coming on the market, and even dedicated printerheads capable of working with silicone and similar materials... How long until you can print replicas of 'anatomical details' of actors/actresses?

    'Ribbed for your pleasure'...

      Re: Digital photography and inkjets...

      Inkjets - SWMBO does a lot of craft stuff which involves printing stupid amounts of stuff - full page patterns as well as inidividual design elements.

      I bought a reasonable Canon printer and a continuous ink system from EBay which feeds ink to it from a set of bottles through silicon tubing. Over the last two years I've had four sets of 5x100ml/colour ink bottles through it at about £35/set, and the only issues are that I occasionally had to re-prime it (it works using the syphon principle, no pumps or moving parts). Wear gloves and don't mess with it over a carpet you need.

      If you print a lot (at least several times a week) then it's well worth giving it a go. 500ml of ink in individual cartridges would cost you several hundred pounds...

      Once, I had a manual SLR.

      It had a ground glass focussing screen with a split image. One control and my focus was OK.

      Now I have a DLSR, which can select from - using 3 independent controls - over 60 different ways to focus the shot.

      Frankly if my eyes weren't shot I'd still be using manual focus.

      Its like a microwave oven with 30 buttons to press, none of which actually result in power being applied to the magnetron.

      I am sticking to my £45 one that says 'power level' and 'time'

    I recently bought a 3d printer personal prototyping/model making

    I recently spent around 1000$ on a cheap 3d printer and parts. Now I wouldn't of went bought one if I didn't already have experience with 3d modeling and cad. I had wanted one for years to play around with building working mechanical models of concepts. Mostly for my own enjoyment.

    While I wasn't going to splash out on a makerbot or a 10k + stratasys stereo lithography machine. I was willing to buy a cheap 600$ model, Since I was sure to have to upgrade grade and modify it. At roughly 30$ a 1kg roll for PLA and 40$ for a 1kg roll of ABS, it seemed an acceptable cost. While admittedly I have wasted about 1kg of filament on learning. I have also made functional parts, like roller bearing assemblies. Which I ended up putting to use on a wire storage rack. I have also built some small high fairly high precision Clutch assemblies for RC cars. Even have gone so far to be working on an almost entirely 3d printed RC plane. While my biggest challenge is build volume at this size of printer. The parts are quite strong and functional. If anything it has been a great Hobby to keep my mind off work problems, while providing a bunch of creative problem solving possibilities. Not to mention Its quieter than being out in the garage at 3am with the table saw and a air compressor running.

    I think it's going to take a while before 3D printing at home becomes more than an expensive hobby.

    I doubt it's going to revolutionise printing and kickstart home production the way the stamp/pic/avr/arm chips have opened up to the home market in the near future.The price of entry and running is to high at the moment.

    What I do expect is it'll stay more like a bureau service for a while, much like the laser etching/cutting and pcb bureaus. The bureaus will have the higher end machines so you get a better quality finish and as long as the turn-around and price are sensible it seems a more likely route for the near future.

    I can think of a few things that for myself could be useful printed, but i'm not spending £500-£1000 on a printer to do it. Even then I think the finish will leave a lot to be desired.

    Whether they'll become useful mass market devices or just be the printing version of a knitting machine only time will tell.

    How about weapons designed for 3D printing?

    Perhaps a new take on the old pepperbox style revolvers, where the cylinder/barrel is easily replaceable

    1. Nigel 11

      Re: How about weapons designed for 3D printing?

      I think the question is why try to make a gun barrel out of printed plastic, when machined metal is so much better (ie, so much less likely to blow the shooter's hand or face off, to say nothing of having rifling that's still there after the first shot).

      I'm trying to think of any advantages a 3-D printer might give for the construction of bows or crossbows, but I can't think of any..

      1. Frankee Llonnygog

        Re: How about weapons designed for 3D printing?

        A one-use barrel might be safe enough - though I guess if it was, Gilette would be in the weapons business

    And most could not understand what anyone could possibly do with a personal computer in their home. How about we let the market decide what uses these oozing plastic machines are good for and leave the naive judgement out of it for a wee bit longer?

    1. Alistair Dabbs

      personal computer in their home

      Ah now this gets to the crux of the matter and one of the themes of this week's column.

      Did any home in the 1970s and early 80s have any use for a personal computer? Hey, I'd have loved an Intel i7 ultrabook connected to the Internet by IEEE 802.11n in 1980 ... but you know what? All they had were BBC Micros and ZX Spectrums, which were of NO use to the average home, unless you include being able to play a version of Pong as "useful".

      So my observation is that I'm sick of people telling me how orgasmic 3D printing is when it isn't... yet. Sure, I could let the market decide, which is another way of saying: "Don't tell anyone how crap the products are at the moment! Let them spend their money based on wild rumour and misleading PR and then find out for themselves!" It's an interesting approach but not one that I subscribe to.

    thermoplastic turds

    " whizz-whir desktop 3D printers that produce a range of useless, multi-coloured, thermo-plastic turds."

    spot on. really sums up the whole thing.

    apart from some level of initial prototyping , possibly.

    I did see a thing on tv where the military claimed to be making huge saving by using 3d printing - somthing to do with aircraft parts, but i think they were talking out of their arses. They;re not known for thrifty savings.

      You guys are ignorant fuckheads. I know that makes me sound like a yank but... you've driven me to it. Keep reading and researching. You are espousing the 3D-printing view from about 1995. It's not 1995 anymore. No, really, look out the window.

    Re: What do my rootin’ tootin’ gun nut owning American colleagues think?

    This one thinks there's a good reason every proof of concept I've seen covers everything but the barrel.

    So we'll be printing worth-more-than-one-shit rifled gun barrels right around never.

    too cheeky

    Would have been a much better article with out all the crap about rowdy, mustached Americans. My grandfather (on my mum's side), who was a Brit, had a mustache. Whereas in all the photos of my father's side (mostly Americans back to the founding fathers) there isn't a single mustache until you get back to the 1800's. As a gun owner, I do not have a mustache either. The "tea party" comment was the one that made me write this. It confirms your ignorance of the "party" and thus your ignorance on firearms in general. Thus the whole article is a waste of digital space.
